To ctll/ w/wm it may concern-.-

Be it known thatl, GEORGE E. WOODBURY, a citizen of the United States,residing in the city and county of San Francisco, in the State ofCalifornia, have invented a new and useful Improvement in Ore-Cars, ofwhich the following is a specification.

This invention relates to improvements made in cars for hauling anddumping coal and ore; and the invention embraces certain novel parts andcombination of parts, as hereinafter described, and pointed out in theclaims at the end of this specification, reference being hadtotheaccompanyingdrawings, forming part thereof, in which- Figure l is aside elevation of an ore-car embodying my present improvements. Fig. 2is an elevation taken from the left-hand side of Fig. 1. Fig. 3 is a topview of a portion of the car-body and the door, showing one of thelocking-cams and its rotating mechanism. Fig. 4: is a top view in detailof the lockingcam, with a portion of the car body and door in detail.Fig. 5 is a front view of the fastening that holds down the front end ofthe carbody and releases it for tilting.

The door at of the car-body b swings outwardly on hinges composed ofears d 61, extending rearwardly and horizontally at the sides of thebody, and ears or lugs e e on the door, united by bolts f f, the doorbeing arranged at an angle from the vertical, so as to throw the bottomof the door beyond the vertical plane in which the points f faresituated.

The body I) is mounted on its truckg in the usual manner on a turn-tableto which it is hinged, so as to tilt from the side as well as from therear, the tilting-point 2' being situated at or near the rear end of thetruck.

The door-controlling device employed is an improvement on that class ordescription of such devices which are operated by or from the tiltingmovements of the car-body to release the door as soon as the bed of thecar reaches and makes such an angle with the track that the principalweight of the load has accumulated on the rear end of the body. ()n thereturn movement, after the dumping operation, the door is closed andlocked in the same automatic manner.

In my present improvement the locking device is constructed of acam-shaped rotary dog m, fixed in the outer end of a rotary shaft n, forwhich bearings 13 pare provided on the side of the car-body. This shaftextends from the door to a point near the tilting center of the car-bodywith which it would coincide if prolonged and is set at a greater orless angle, according to the position of the locking-cams. Theselast-named parts are fixed in the projecting outer ends of the shafts,and each one is formed with a flat inner face 8, lying in the same'plane with the door, and also with an oblique or outwardlybeveled face25, extending out to the point. This beveled portion is curved, as shownin Figs. 2 and 3, on a spiral increasing from the center of rotationoutward. A pinion a, fast on the lower end of the shaft and engaging astationary toothed segment 10, is rotated by the movementof the car-bodyboth in the dumping operation, as the car is tilted backward, and alsowhen the car is brought up to horizontal position for reloading. Therack is stationary on the truck and is fixed in such position that thecar-body will clear it when turning around on the center bolt and is ofproper length also to hold the gear in mesh with it in all positions ofthe car -body. One of these locking-cams and its operating-shaft andgearing are placed on each side of the carbody,and the two are geared tooperate simultaneously, looking or releasing the two sides of the doorat the same moment. The racks to are supported from the rod or shaft 11,that connects the car-body to the turn-table, the ends of that shaftbeing prolonged beyond the ears or knuckles r of the hinge, so as tosupport the racks at the sides of the car-body.

The position of the locking-cams can be changed to hold the door atpoints nearer the bottom by setting the rotary shaft at a lesser anglefrom the horizontal than is shown in the drawings.

The forward end of the cards held down by a catch of novel constructioncomposed of a footlever l, pivoted in a bracket 2 on the front extensionof the truck and having an upright member 3, terminating in ahook-shaped head 4:, the point and shoulder of which are shaped to enterand engage a slotted hanger 5 on the car-body. The lower end of thishanger is formed with inwardly slanting edges 6 6, meeting together inan acute point under the opening for the hook and having the same angleas the sides of fixed guides 7 on the truck. These last-mentioned partsare fastened on the truck in such position that when the car-body isdirectly on the longitudinal central lineof the truck the hook of thecatch is in line with and Will engage the opening in the hanger; butshould the carbody be slightly oil the center, as often happens inbringing it to the horizontal position after dumping,the point of thehanger will strike the inclined faces of the guides and bring the bodyinto place on the center to be caught and locked. This improvedconstruction of latch, among other advantages, prevents much waste oftime in bringing the carbody back and setting it exactly on the centerof the truck before it can be locked.

Having thus fully described my invention, What I claim as new therein,and desire to secure by Letters Patent, is

1. In an ore-car, the combination with a truck and a tilting car-bodymounted thereon, of a hinged door, rotary shafts having hearings on thesides of the car-body, a stationary rack on each side of the truck, agear on the shaft in mesh with the rack adapted to be rotated by rollingcontact with the rack,

and a locking-cam on the outer end of each shaft having curved endsprovided with beveled inner faces.

2. In a device for automatically locking and releasing the door of atilting ore or coal car from the movement of the car-body on the truck,the combination of a rotatable shaft mounted on the car-body, alocking-cam fast on said shaft adapted by its rotation to engage anddisengage the door, a rack stationary on the truck, and a gear fast onthe shaft engaging the rack to rotate the shaft by rolling contact withthe rack.

3. In an ore-car the combination with the truck and a tilting bodymounted thereon;

of the locking-catch, hanger having an opening for the catch andinclinedfaces on opposite sides of said opening and meeting on the center of thehanger beneath the opening, and the fixed angular guides on oppositesides of the catch.

In testimony that I claim the foregoing I have hereunto set my hand andseal.
